Leak from transfer case and rear shaft

[laprodigy001]

Hello I just noticed I have a pretty bad leak on the rear of my transfer case. It's right where the rear drive shaft goes into the transfer case. It seems to be coming from the rubber that's stocked out on it. Here is a pic.

I actually just saw a video on this. It's 20 bucks and an hour of time to replace the seal.

I see that its a rear output shaft seal ,but can't seem to find it anywhere local. My transfer case is the 246gm with the electric push button. Also I was reading o line that my tcase takes autotrac 2 fluid. But in my book that was in the glove box states it takes auto trans fluid. The book is the original book that came with the truck.

Thank you

The blue auto tracII fluid is what you want. There is a TSB about it somewhere. GM originally spec'ed out ATF fluid but changed it up later. I've run both (due to two different shops putting the wrong stuff in). I just change all my fluids myself and know the right stuff is in there now.

Where is the best place to buy the Auto Trac II fluid?

Can you notice a difference when you have the blue auto trak fluid in? I will be changing my t case fluid to auto trak very soon. I just need the rear transfer case output seal first.

Is there a
